Invoice Prefix is the information positioned in-front of the Invoice Number, we use “INV -” as your default. You can change this to whatever your company would prefer.

We can automatically increase the Invoice number sequentially for you. You may want to start doing this from a particular Invoice number, please enter those details in the invoice settings otherwise the system will start from INV-00001.
